I made some web-based GB/GBC ROM tools

I’m currently developing some web-based tools for GB/GBC ROM editing and reverse engineering.

Current tools:

- GB/GBC Pointer Calculator

- GB/GBC Hex Editor

The goal is to create lightweight browser-based tools that work without installation.

Features:

- Runs directly in the browser

- No installation required

- Local file processing

- Designed for ROM hacking and retro game research

Still improving the UI and features, but the tools are already functional.
